Required Technical Competencies

DOE-STD-1161-2003

Experience:

Industry, facility, operations, or other related experience and/or a Professional Engineer license

that has provided a background in mechanical engineering. Specialized experience can be

demonstrated through possession of the competencies outlined in this Standard.

REQUIRED TECHNICAL COMPETENCIES

Each of the competency statements defines the level of expected knowledge and/or skill that an individual

must possess to meet the intent of this Technical Qualification Standard. The supporting knowledge

and/or skill statements further describe the intent of the competency statements but are not

requirements.

Note: When regulations or Department of Energy directives or other industry standards are referenced

in the Qualification Standard, the most recent revision should be used.

Mechanical systems personnel shall demonstrate a working level knowledge of steady-state

heat transfer.

Supporting Knowledge and/or Skills

Define:

Conduction

Convectivity

Discuss Fourier's law.

Describe the factors that contribute to the co-efficient of thermal conductivity.

Calculate the heat flux for one-dimensional, steady-state heat transfer through the

following:

Composite wall

Series wall

Parallel wall

Using data, calculate total heat transfer and local heat flux in a laminar flow system.

Using data, calculate the log mean temperature difference for heat exchangers.

Mechanical systems personnel shall demonstrate a working level knowledge of the

construction and operation of heat exchangers.
